Is the risk of breast cysts becoming malignant high?

Breast cysts are generally not prone to malignant transformation, but their changes need to be closely monitored and regular follow-up is required to ensure health.

Breast cysts are fluid-filled cystic structures formed in breast tissue. They are common in women, especially in the reproductive age group. The vast majority of breast cysts are benign and are mainly affected by hormone fluctuations in the body, especially changes in estrogen levels, which may lead to the formation of cysts. Some women may feel breast pain before menstruation or even feel slight tenderness when touching the cyst site, which is a typical manifestation.

Cysts with a low risk of malignant transformation usually have the following characteristics: smooth edges, fluid inside, and stable size or fluctuations with the menstrual cycle. However, if the cyst suddenly increases in size, becomes irregular in shape, or is accompanied by other abnormal symptoms, such as nipple discharge (especially bloody) or changes in the breast skin, it needs to be taken seriously. Although the risk of breast cysts becoming malignant is low, long-term irregular examinations may increase the possibility of overlooking early lesions.

If you find a breast cyst, don't panic. It is recommended to conduct regular breast ultrasound monitoring, usually every 6 to 12 months. If the cyst is large or the symptoms are obvious, you can choose puncture drainage or drug treatment under the guidance of a doctor. If accompanied by abnormal symptoms, you need to see a doctor in time, and the doctor will assess whether further examination is needed, such as a puncture biopsy. Maintaining a healthy lifestyle, moderate exercise and an optimistic mood can help reduce the frequency of breast cysts.
